      I don’t get how this pump configuration works. Would it not just clamp down on the hose and drag it and jam (clearly not but...)pic.twitter.com/CZHFPaiUoQ

      A peristaltic pump? There are usually rollers or some other friction-reducing devices at the contact points. https://en.wikipedia.org/wiki/Peristaltic_pump …

          Looks like that one uses lubricant instead. I guess the surfaces are engineered to be low friction. http://www.watson-marlow.com/Documents/knowledge-hub/Manuals/us%20-%20USA/Bredel/m-bredel%2010_20-us-03.pdf …

          oh interesting PDF... yep looks like it. I wonder what the advantage of that is... feels like it would give less flexibility in terms of tube materials etc...
